Chapter 8. Introduction to Optimization
To improve the quality of the code that it generates, an optimizing compiler analyzes the code and rewrites it into a more efficient form. This chapter introduces the problems and techniques of code optimization and presents key concepts through a series of example optimizations. Chapter 9
expands on this material with a deeper exploration of program analysis. Chapter 10
provides a broader coverage of optimizing transformations.

The compiler's front end translates the source-code program into some intermediate representation (
ir). The back end translates the
ir program into a form where it can execute ...
